Botanical Name: Hemerocallis darrowiana
*Cameraria Boehm. in C.G.Ludwig
Common Names: Daylily or Day lily
Habitat: Hemerocallis is native to Asia, primarily eastern Asia, including China, Korea, and Japan. This genus is popular worldwide because of the showy flowers and hardiness of many kinds.
Hemerocallis darrowiana is a perennial flowering plant, growing to 0.1 m (0ft 4in).
It is not frost tender. The species is hermaphrodite (has both male and female organs) and is pollinated by Insects.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers dry or moist soil.
Succeeds in most soils including dry ones, preferring a rich moist soil. Grows well in heavy clay soils. Succeeding in sun or shade, it produces more flowers in a sunny position though these flowers can be shorter-lived in very sunny positions. Succeeds in short grass if the soil is moist. Prefers a pH between 6 and 7. This species has not been grown in Europe but, coming from the island of Sakhalin in N. Japan, it should prove to be hardy in most parts of Britain. Individual flowers only live for one day. The plant produces short scapes with only two flowers on a scape. Hybridizes freely with other members of this genus. Plants take a year or two to become established after being moved. Plants seem to be immune to the predations of rabbits. The plants are very susceptible to slug and snail damage, the young growth in spring is especially at risk.
Leaves and young shoots – cooked. They must be consumed when very young or else they become fibrous. Flowers and flower buds – raw or cooked. A flowering stem bears two trumpet-shaped blossoms, each about 6cm long and 6cm in diameter. The flower buds contain about 43mg vitamin C per 100g, 983 IU vitamin A and 3.1% protein. If this species has swollen roots then they can be eaten raw or cooked.
Medicinal Uses: The juice of the roots is an effective antidote in cases of arsenic poisoning. A tea made from the boiled roots is used as a diuretic.
Other Uses: The tough dried foliage is plaited into cord and used for making footwear. Attractive flowers.
Known Hazards: Large quantities of the leaves are said to be hallucinogenic. Blanching the leaves removes this hallucinatory component. (This report does not make clear what it means by blanching, it could be excluding light from the growing shoots or immersing in boiling wate.
